A quality product (by the looks of it) with the added bonus of heatsinks for smaller chips. Since 2B I've been using solid copper fins on older RPi boards. Always questioned the need for a CPU fan, but this Enokay fan brought temperatures down even further. Best of all are two notable elements: you no longer have to leave the lid open to get a couple of degrees of drop, and the fan is thin enough to fit in with the lid closed.
